Detailed explanation of wind turbines from wind speed benefits to safety considerations

Generally speaking, for wind turbines, three-level wind has utilization value. But from an economically reasonable perspective, wind speeds greater than 4 meters per second are suitable for power generation. According to measurements, when the wind speed is 9.5 meters per second, the output power of a 55 kW wind turbine is 55 kW; When the wind speed is 8 meters per second, the power is 38 kW; When the wind speed is 6 meters per second, it is only 16 kW; When the wind speed is 5 meters per second, it is only 9.5 kW. It can be seen that the stronger the wind, the greater the economic benefits.

In our country, there are many successful small and medium-sized wind power generation devices in operation now.

China has abundant wind resources, with an average wind speed of over 3 meters per second in most regions, especially in the northeast, northwest, southwest plateaus and coastal islands where the average wind speed is relatively high; In some places, more than one-third of the time is a strong wind day. In these regions, the development of wind power generation is very promising.

Wind is one of the pollution-free energy sources. It is inexhaustible and inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas, and plateau regions with water shortage, fuel shortage, and inconvenient transportation, utilizing wind power according to local conditions is very suitable and has a bright future.

But it doesn't mean that the higher the wind speed, the better, because rotating the wind turbine too fast may cause the machine to overheat, damage, or lose control, posing serious safety risks. In addition, high-speed rotating blades may pose risks to surrounding birds and other wildlife. Therefore, in order to ensure the stability, safety, and reliability of wind turbines, the speed should be carefully considered and controlled during the design, operation, and maintenance process.
